Whatβs Included in the Workshops?
MODULE 1
Mindset & Confidence
Everything starts in the mind. In this module, youβll discover how your thoughts, focus, and beliefs directly influence how you perform β on the court, at work, and in life. Youβll learn not only what happens in your mind, but more importantly, how to consciously take control of it.

β The identity shift: from doubt β to confidence
β Solid self-confidence that doesnβt collapse after mistakes or setbacks
MODULE 2
Emotions & Focus
Pressure, tension, and emotions are part of performance. But they donβt have to determine how you play, choose, or act. In this module, youβll learn how to recognize, regulate, and use emotions as a source of strength β instead of being carried away by them, on the court and beyond.

β The 90-second rule to quickly reset emotional reactions

β The ability to recover immediately after mistakes β without self-criticism
β Focus that helps you return to the present moment and the process
MODULE 3
Dreams, Goals & Direction
True motivation arises when you know why you do what you do β and when your actions are aligned with that bigger vision. In this module, youβll gain clarity about your direction and learn how to translate big dreams into concrete, achievable steps in sport, work, and life.
This module helps you avoid getting lost in goals, and instead move forward with direction, confidence, and consistency. Not working harder β but living and performing with greater focus and purpose.
Β
You will develop:
β Clarity about what truly drives you
β The ability to set meaningful goals that energize you
β The difference between outcome goals and growth goals
β Focus on daily actions that create long-term impact
β The βMountain Path Methodβ: staying on course, even when things get challenging
MODULE 4
Connection & Joy
True performance doesnβt arise from pressure or control. It emerges when you are connected to yourself, to others, and to what you do. In this module, youβll discover how connection creates greater joy, resilience, and confidence β on the court and beyond. Youβll learn to play and live from presence, instead of pressure.
This module helps you play freely again β with courage, joy, and meaning β without losing yourself in expectations.
Β
You will develop:
β Connection with yourself β recognizing what you need and trusting it
β Connection with others β teammates, coaches, and parents, even under pressure
β The ability to perform from joy instead of fear
β Greater ease, freedom, and natural motivation
β Resilience and emotional strength through genuine engagement
This workshop is for you ifβ¦

β You long for calm, clarity, and confidence, without forcing yourself
Β
This doesnβt mean youβre weak. It means youβre ready to consciously train your mental game.
In this workshop, youβll learn how to work with thoughts, tension, and emotions β so you stay present, even when it truly matters. Not by trying harder. But by choosing your response with awareness.
Β
The result?
More inner calm. More process focus. More confidence in yourself β under pressure.
Yes β this is truly possible.
YES, IβM IN!NICE TO MEET YOU
Iβm Bastiaan Kollen.
I grew up on the tennis court β playing, learning, making friends, and enjoying the game. Sport gave me joy, confidence, and discipline. But in my twenties, I discovered something just as powerful: the mindset behind performance.
I became fascinated by one question: why do some people or athletes freeze under pressure, while others rise above themselves?
And I realized:
Mindset makes the difference.
Since then, Iβve dedicated my life to understanding the human mind β through NLP, psychology, coaching, and high-performance training.
Today, I help athletes, coaches, and professionals develop the tools I once wished I had: confidence, emotional control, focus, and above all, joy in the game.
Β
My mission is simple: To help people train their minds β so they can become the champion of their own game and life.
βCoach, isnβt everything just the story you tell yourself? If I tell myself Iβm old, Iβll feel old. But if I tell myself Iβm growing and that Iβm worthy, then Iβll play like it too.β

βBastiaanβs mental coaching was the breakthrough my son truly needed β both on and off the court.β
